Abbrev

Given a set of strings, calculate the set of unambiguous abbreviations for those strings, and return a hash where the keys are all the possible abbreviations and the values are the full strings.

Thus, given +words+ is "car" and "cone", the keys pointing to "car" would be "ca" and "car", while those pointing to "cone" would be "co", "con", and "cone".

Installation

Add this line to your application's Gemfile:

gem 'abbrev'

And then execute:

$ bundle install

Or install it yourself as:

$ gem install abbrev

Usage

require 'abbrev'

Abbrev.abbrev(%w{ car cone })
#=> {"ca"=>"car", "con"=>"cone", "co"=>"cone", "car"=>"car", "cone"=>"cone"}
